The BBC's Alex Last in Lagos says the death toll may be far higher. There is no figure for the number of injured. The local imam at the mosque where Muslims brought their dead said the number was in the hundreds.

At the Vatican, Roman Catholic Church leader Pope Benedict included Nigerian victims in his prayers on Sunday and urged the world to express "horror and disapproval" at the senseless violence.

Political power

Army spokesman Brig Emeka Onwamaegbu earlier told AFP news agency that there were no more violent incidents on Sunday, but Oxfam co-ordinator Francis Ayinzat told the BBC he heard gunshots before leaving the town for the capital, Abuja. "There is a very severe shortage of medical supplies, and a lot of people are going without water," Mr Ayinzat said.

Violence flared up on Friday after the mostly Christian-backed governing party, the People's Democratic Party, was declared to have won the state elections in Plateau state, of which Jos is the capital city.

The result was contested by the opposition All Nigeria People's Party, which is perceived in the state as a predominantly Muslim party.

Jos has seen repeated bouts of inter-communal violence, with more than 1,000 killed during riots in 2001.

The real trigger for the violence is usually competition for resources, our correspondent says.

And in Nigeria political office is perhaps the most powerful resource of all as it gives the holder access to some of country's huge oil revenues.
